C = 2 * (pi) * (radius) So plug in 2 for radius C = 2 * (pi) * (2) C= 4(pi) If you need to approximate multiply 4 times 3.14. If you do not need to approximate then your answer is 4(pi)

Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is the circumference of radius equals 18 in?
C = 113 inches.
What is the circumference of the circle with a 6 inches radius?
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
What is the radius of a circle if the circumference equals 17cm?
radius = 17/(2*pi) = 2.705634033 or 2.706 cm to 3 d.p.
Radius from circumference?
The radius is 1/2 of the circumference.
If radius equals 2.25meters what is the circumference?
If radius equals 2.25 meters the circumference is: 14.1 meters.
Diameter equals 4cm so cicumference equals?
radius = 2cm circumference=2(pi)r 2(22/7)2 88/7 12 4/7cm
What is the circumference of the 2cm?
2 x pie = 6.2
Radius equals 2.4 what is the circumference?
If a circle's radius is 2.4 its circumference is: 15.1
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is the circumference of a circle if the radius is 12?
The circumference of a circle if the radius is 12 equals about 75.4
What fraction of a circumference equals the radius?
2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
What is the radius of a circle when the circumference equals 66?
The radius is 10.5
What circumference equals radius 8?
Circumference = (pi) x (diameter) Diameter = 2 x radius
What is the circumference if radius equals 3 cm?
The circumference = 18.8 cm
What is the circumference of a circle when the radius is 25 ft?
The circumference of a circle when the radius is 25 feet equals about 157.08 feet.
What is the length of the radius if the circumference equals 18x3.14 for pie?
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
